Exhaust question

[Archangel]

A cop car will very likely have the same shit as yours, now a cop-owned car is a different animal - I got my catless H-pipe setup off a cop-owned Grand Marquis, the car had all the goodies an interceptor would have + some extras (an HO motor and the aforementioned custom-bent dual catless exhaust).

A Mustang H pipe is up front, and contains the catalytic converters. It also won't bolt to the stock Panther manifolds, so you'll need either aftermarket Mustang shorty headers, or stock headers from a Mustang or Mark VII. A Panther H bolts behind the cats. The stock H pipe necks down to 2" literally an inch ahead of the flanges. You could have an exhaust shop cut the cat pipes just ahead of the stock flanges, install larger ones, and make up a 2.25" H pipe to run behind the stock cats. This will let you keep the stock manifolds.

I wouldn't suggest snagging used exhaust parts since most of the time you'll be getting 10-15 year old garbage thats ready to fall apart. Either have a larger H pipe made and keep your stock catalytic converters, or ditch the entire existing exhaust, use headers, an H or X designed for a Mustang (X pipes work fine), and piping back from that point. It will be more work if you're doing an engine back exhaust, and more money however you'll end up with bigger exhaust. Honestly, if you're running a stock motor, having a 2.25" H pipe made up, and installing better mufflers and possibly larger over-axle pipes will do you just fine. Stock Impala tails are 2.25" and will work well for you.

Thanks for the explination Gadget. I've been browsing around and I found a set of FRPP headers that claim they will bolt to a stock exhaust, so I'm assuming the collectors are 2.25"? If I bought these, I'd probably run a Mustang H-pipe with the Impy tails. Does anyone have any suggestions as to different headers or good aftermarket H or X pipes?

Just buy the Flowmaster mufflers and piece the rest of the exhaust together. I went with a custom X-Pipe (welded on), "original" Flowmaster 40-series mufflers, Impala SS tail pipes and Maruader tips on my car. I LOVE that sound!!!

Will bolt to stock exhaust on what? Mustangs or a Vic? Most Mustang shorty headers will technically bolt to stock exhaust.

[88MercWagon]

Sorry, they meant stock exhaust on a Mustang. I guess I'm going with a set of shorty headers, stock Mustang H with new cats, and Impy 2.25" tails. Other than the FRPP's, what are some other good headers?

[88MercWagon]

Hold the press, I just found a set of cheap mid-length headers for a Mustang on E-bay

Would these fit? I know long tubes wont fit a Panther, but how about these bad boys? Do they make a differnce in powerband over shorties?

:bump:

Those pics and that description do not go together. The probably wouldn't fit anyway.

BBK shorties are nice, and inexpensive.

[88MercWagon]

Arite, thanks man. Sorry to be such an annoyance, I'm just picky and try to look at all the possibilities when it comes to stuff like this.

[mrltd]

One of the guys here modded headers similar to that to fit...could have made custom ones with the amount of work needed to make them fit.

[88MercWagon]

Would there be a powerband difference with mid-lengths like that?

[mrltd]

if there was I doubt it'd be noticable...

[88MercWagon]

Alrighty then, BBK or FRPP headers, Stock Mustang H-pipe, Impy tails with Flowmaster Delta 40's...nice

Tell me what the Delta mufflers sound like. I have original 40-series mufflers and I love them!!!
